Attitude estimation for pedestrian navigation using low cost mems accelerometer in mobile applications, and processing methods, apparatus and systems

TL;DR: In this paper, a user-heading determining system for pedestrian use includes a multiple-axis accelerometer ( 110 ) having acceleration sensors; a device-heading sensor circuit ( 115 ) physically situated in a fixed relationship to the accelerometer, and an electronic circuit ( 100 ) operable to generate signals representing components of acceleration sensed by the acceleration sensors, and to electronically process at least some part of the signals to produce an estimation of attitude of a user motion with respect to the acceleration sensor, and further to combine the attitude estimation ( 750, α) with a device heading estimation ( 770

Methods and systems for determining vascular bodily lumen information and guiding medical devices

TL;DR: In this paper, the authors describe methods and systems for determining information about a vascular bodily lumen using an electrical signal, delivering the electrical signal to a plurality of excitation elements in the vicinity of the vascular lumen, measuring a responsive electrical signal from the sensing elements in response to the delivered electrical signal and determining a lumen dimension.

Robust step detection using low cost mems accelerometer in mobile applications, and processing methods, apparatus and systems

TL;DR: In this article, a system for pedestrian use includes an accelerometer having multiple electronic sensors; an electronic circuit (100) operable to generate a signal stream representing magnitude of overall acceleration sensed by the accelerometer (110), and to correlate a sliding window ( 520 ) of the signal stream with itself to produce peaks at least some of which represent walking steps, and further operate to execute a periodicity check ( 540 ) to compare different step periods for similarity, and if sufficiently similar then to update ( 560 ) a portion of the circuit substantially representing a walking-step count.
